YDP-1F, 20F Type Differential Pressure Control Valve
This maintains the differential pressure of supply and return lines or the differential pressure of
the inlet and outlet side of an instrument in a closed circuit.
Features
• As an air-to-close differential pressure valve, it has a structure where the valve opens when the primary
pressure goes up. It is installed in between the supply header and return header to control the differential
pressure.
• As a self-control type, it does not require auxiliary power supply.
• As a complete balancing type, almost no changes in the set differential pressure resulting from pressure
fluctuations.
• Structure is relatively simple, and offers superb durability.
• Convenient piping and handling.
• Separated diaphragm from the main body, not affected by temperature, resulting in outstanding durability.
